2. Gas permeation membranes
2.1 Mechanism and modeling of gas permeation
The transfer of a gas through polymers results from a solution-diffusion mechanism, with the gas first dissolving in the polymer phase before being transported by a diffusion process.
The permeation rate of a gas through a polymer is therefore described by Fick's law:
